<br> Indeed, at this point we are not aware of any performance problems. Of course all the features we added may add a bit of overhead, but in our tests that was completely offset by the improvements we made. The elimination of shadow facts by itself is a huge boost for use cases with lots of facts or facts with many fields. (just to mention one case)<br>
<br> Keep us posted and if you submit more info, please include the actual versions of the jars you are using of Drools and MVEL.<br><br> Edson<br><br> <br><br><div class="gmail_quote">2009/5/28 Scott Reed <span dir="ltr"><<a href="mailto:sreed@avacoda.com">sreed@avacoda.com</a>></span><br>

I figured I must have missed some docs explaining changes required
for the upgrade. If I suspected this was an inherent problem with the
5.0 release I'd have supplied lots of info. I am inferring from the
response that there are no known issues with 5.0 upgrade so I'll do my
own investigation for a while. Let's hope I find something unrelated to
the Drools.<br><font color="#888888">

As others already mentioned, your e-mail does not help much. We need
to know what is "unacceptably slow". How much slower is that? 10%,
100%, 1000%? Also, we need a description of your use case: what kind of
rules do you use, how many rules, how many facts, etc. Finally, we need
a way to reproduce the problem.<br>
<br>
So, if you can provide more info, we might be able to help. <br>

just upgraded our app from Drools 4 to 5 libraries. We just use the
rules engine with DRL. The performance of the engine on our rulebase is
unacceptably slow. I assume there is something we need to do to our
rules or the way we are configuring the engine to fix this. I don't see
anything in the release notes about backwards compatibility issues. I
would very much appreciate it if someone would direct me to any
documentation that explains what needs to be done so our 4.0 rules
perform at least as well as they did before the upgrade?<br>
Thanks,<br>
